maven - 将S3存储桶用作带有Gradle的Maven私有(private)存储库

Question

我正在尝试使用AWS S3作为Maven私有(private)存储库..以下是我的build.gradle看起来像-:

import java.util.regex.Matcher
import com.amazonaws.auth.AWSCredentials;
import com.amazonaws.auth.profile.ProfileCredentialsProvider;

buildscript {

repositories {
    mavenCentral()
}
dependencies {
    classpath 'com.amazonaws:aws-java-sdk-core:1.11.5' 
}
}



plugins {
id "java"
id "idea"
id "eclipse" //run "./gradlew cleanEclipse eclipse" after importing to eclipse
id "maven-publish"
id "maven"
id 'base'
id 'signing'
id 'jacoco'
id "net.researchgate.release" version "2.4.1"
id "org.springframework.boot" version "1.5.2.RELEASE"
}

def fetchAwsCredentials = {
try {
    return new ProfileCredentialsProvider().getCredentials()
} catch (Exception e) {
    logger.debug('Unable to retrieve AWS credentials from profile, publishing to S3 will not be available.', e)
        return null
}
}

AWSCredentials awsCredentials =  fetchAwsCredentials()


repositories {
mavenCentral()
maven {
url 'xxxxxxxx/<Bucket-Name>/snapshots/'
credentials(AwsCredentials) {
               accessKey awsCredentials.AWSAccessKeyId
               secretKey awsCredentials.AWSSecretKey
}
}
}


publish {
dependsOn assemble
}


publishing {
publications {
    maven(MavenPublication) {
        groupId this.properties['group']
        artifactId this.properties['mavenArtifactId']
        from components.java
    }
}
repositories {
    maven {
        name 'repo'
        credentials(AwsCredentials) {

              accessKey awsCredentials.AWSAccessKeyId
              secretKey awsCredentials.AWSSecretKey

        }
        if (project.version.endsWith('-SNAPSHOT')) {
            url "xxxxxxxx/<Bucket-Name>/snapshots/"
        } else {
            url "xxxxxxxx/<Bucket-Name>/releases/"
        }
    }


}

}   

但是我正在错误以下

似乎由于在gradle jar-中添加的条件不正确而失败:

有任何线索吗？

您面临的问题是错误的S3网址格式。

从基础Credentials接口(interface)扩展了两个接口(interface)。

AwsCredentials

密码凭证

当您使用 url 'xxxxxxxx/<Bucket-Name>/snapshots/'时，它会将Maven存储库检测为正常的URL。这就是为什么它要求 PasswordCredentials的原因。

您应该使用 s3://<bucket-name>.s3-eu-west-1.amazonaws.com。在这里它将要求 AwsCredentials。

恕我直言，您应该对发布和快照使用两个不同的存储桶。

repositories {
    maven {
        name 'repo'
        credentials(AwsCredentials) {
            accessKey awsCredentials.AWSAccessKeyId
            secretKey awsCredentials.AWSSecretKey
        }
        if (project.version.endsWith('-SNAPSHOT')) {
            url "s3://<bucket-name>-snapshots.s3-eu-west-1.amazonaws.com"
        } else {
            url "s3://<bucket-name>-releases.s3-eu-west-1.amazonaws.com"
        }
    }
}
